      Introduce an LXC specific public API & library · 3d1596b0
      Daniel P. Berrange 提交于
      This patch introduces support for LXC specific public APIs. In
      common with what was done for QEMU, this creates a libvirt_lxc.so
      library and libvirt/libvirt-lxc.h header file.
      
      The actual APIs are
      
        int virDomainLxcOpenNamespace(virDomainPtr domain,
                                      int **fdlist,
                                      unsigned int flags);
      
        int virDomainLxcEnterNamespace(virDomainPtr domain,
                                       unsigned int nfdlist,
                                       int *fdlist,
                                       unsigned int *noldfdlist,
                                       int **oldfdlist,
                                       unsigned int flags);
      
      which provide a way to use the setns() system call to move the
      calling process into the container's namespace. It is not
      practical to write in a generically applicable manner. The
      nearest that we could get to such an API would be an API which
      allows to pass a command + argv to be executed inside a
      container. Even if we had such a generic API, this LXC specific
      API is still useful, because it allows the caller to maintain
      the current process context, in particular any I/O streams they
      have open.
      
      NB the virDomainLxcEnterNamespace() API is special in that it
      runs client side, so does not involve the internal driver API.
